Political radicalism

Radical politics denotes the intent to transform or replace the principles of a society or political system, often through social change, structural change, revolution or radical reform. The process of adopting radical views is termed radicalisation. The word derives from the Latin ("root") and Late Latin ("of or pertaining to the root, radical"). Historically, political use of the term referred exclusively to a form of progressive electoral reformism, known as Radicalism, that had developed in Europe during the 18th and 19th centuries. However, the denotation has changed since its 18th century coinage to comprehend the entire political spectrum, though retaining the connotation of "change at the root".
